        <asp:TextBox ID="Comments" runat="server" 
                TextMode="MultiLine" Rows="10" Width="400px" />
        <asp:Button ID="btnSubmit" runat="server" Text="Send" 
                    OnClick="Button1_Click" ValidationGroup="save" />
    <asp:Label ID="DisplayMessage" runat="server" Visible="false" />

The server side code:

protected void SendMail()
    // Gmail Address from where you send the mail
    var fromAddress = "";
    // any address where the email will be sending
    var toAddress = YourEmail.Text.ToString(); 
    //Password of your gmail address
    const string fromPassword = "Password";
     // Passing the values and make a email formate to display
    string subject = YourSubject.Text.ToString();
    string body = "From: " + YourName.Text + "\n";
    body += "Email: " + YourEmail.Text + "\n";
    body += "Subject: " + YourSubject.Text + "\n";
    body += "Question: \n" + Comments.Text + "\n";
    // smtp settings
    var smtp = new System.Net.Mail.SmtpClient();
        smtp.Host = "";
        smtp.Port = 587;
        smtp.EnableSsl = true;
        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
        smtp.Timeout = 20000;
    // Passing values to smtp object
    smtp.Send(fromAddress, toAddress, subject, body);

protected void Button1_Click(object sender, EventArgs e)
        //here on button click what will done 
        DisplayMessage.Text = "Your Comments after sending the mail";
        DisplayMessage.Visible = true;
        YourSubject.Text = "";
        YourEmail.Text = "";
        YourName.Text = "";
        Comments.Text = "";
    catch (Exception) { }

The above code has the validation checks also.

This code is based on the 3.5 framework and also works in the 4.0 framework.
